<br />Lower than native flows are typical during the irrigation season (April to October) in <br /> <br />the IS-Mile Reach. Flows at the Palisade gage are typically 1,200 to 1,600 cfs less than <br /> <br />Cameo, except in June when runoff flows from Plateau Creek compensate for diversions into <br /> <br />the Highline canal (Figure A1.3). In Cameo flow generally increases from 2,000 to 4,000 cfs <br /> <br />during the month of April in contrast to Palisade where flows can decrease. in April before <br /> <br />runoff begins (Figure A1.3). <br /> <br />Efforts are currently underway to manage late summer and fall flows in the IS-Mile <br /> <br />Reach to benefitthe recovery of endangered fish. The results of coordinated efforts involving <br /> <br />the BaR, reservoir operators and irrigation companies resulted in increased flows in the 15 <br /> <br />Mile Reach during the 1999 irrigation season (BaR, draft report). <br /> <br />The peak flow (12,700 cfs) for the Palisade gage in 1999 was on June 10 (Appendix <br />0,:, <br /> <br />Figure AI.2). The median peak flow for the nine-year Palisade gage history is 12,500 cfs <br /> <br />indicating that peak flow was near normal in 1999. In 1999 flow during the ascending limb of <br /> <br />the hydrograph were lower than typical (Figure 5). Flow was near the norm of 2,000 cfs <br /> <br />during March, but dropped to 435 cfs on April 15, and did not return to 2,000 cfs until May 2. <br /> <br />Flows at Palisade during summer were near to above the medial conditions, but flows from <br /> <br />mid September through October were typical of a wet year (Figure 6). <br /> <br /> <br /> <br />10 <br />
